Subject: qemu_namespace: Introduce qemuDomainNamespaceSetupPath()
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=5853d707189005a4ea5b2215e80853867b822fd9;p=libvirt.git

qemu_namespace: Introduce qemuDomainNamespaceSetupPath()

Sometimes it may come handy to just bind mount a directory/file
into domain's namespace. Implement a thin wrapper over
qemuNamespaceMknodPaths() which has all the logic we need.
